Looms, of which the following u specification. 7

The present invention consists in unprovements upon the shuttle spring construction illustratcdin United States Letters Patent 1,02d,908, 'Octolocr 7, 191;. In the construction or" that patent the weft carrier holding spring, the weft carrier di rooting guide, and the spreader which maintains the jaws of the spring spaced correctly apart have to be independently handled and assembled in tlie'shuttlea The shuttle spring has to be first put in place and. held by the fastening bolt; the spreader has, to in serted; the guide has to be then put in place and secured by an independent screw.

The object of the present'inveution is v to preliminarily unite the spring. guide and spreader together so that it can be hendled :is a unit and he placed as such in the sshuttle. The combined spring, guide and is s vertical section V lay, the line 3-3 n Fig. 2.' F 1g. l, a

the spring as illustrated in 2,

spreader is then fastened in place by the usual-bolt for the spring.

The improvements are illustrated in U16 accompanying draw Jigs, wherein-- J Figure-1, is a plan View of the weft;- carrier holding end of the shuttle. Fig. 2,

the holes in the shank legs of the spring,

and it is through these holes that the bolt,

shank when the spring, spreaderand guide are assembled prior to insertion in the shuttle The guide 3, has the usual bottom plate (Z, extending beneath the springand fitting slots in the shuttle body as indicated in l ig.. -l. There is also-a top plate 6', this plate andthehettom plate being united together by the! weft carrier diresting incline 0. y The topplate e, is constructed so as to lock the spring, spreader and guide together prior to insertion in the shuttle. l then the spring, spreader and guide are assembled the top plate 6; of the guide is flat The spreader is first placed in position between the legs of the spring and the guide is then putin place with its hot-tom. plate (Z, below the spring and insuring the registration between the hole a, of the spreader and the corresponding holes in the shank legs of the sprin i The end and edges of the top plate 6, are then bent downwardly as illustrated in the draw ings. -The sides 7", are bent downwardly over the upper edges of the shank legs of the spring as illustrated in Fig. l; and the end 9, of the top plate (1, is bent downwardly back of the curved inner end of the spring A, as shown in Fig 3. This cfiectually fastens the spring, spreader and guide together so that their proper relative positiens are insured and the combined parts can then be handled as a unit and can be placed in a shuttle as a single unit.

The united spring, guide and spreader to the shuttle hy the usual single bolt D, which is secured in place in the customary manner.

The bent down sides 7, are bent outwardly at their lower edges to constitute flanges h, whichht within grooves e, of the'shuttle.

(5, it has a hole a, which registers with e this contributing and completing the arrangement to insure positively no movement of the combined parts. .The bent down sides f, compensating for the greater height of the spring shank as compared with the jaws, thus bringing the flanges it, down where they can fit into the grooves z, without danger of fracturing the wood of the shuttle:

' respectively above and below the spring and. spreader, the upper plate being bent at its.

The guide B, with its united bottom and top plates (1 and a, constitutes a bent metal retainer folded around the spring and spreader so as to lock them securely together with their bolt deceiving holes in register. I claim: 1. A shuttle for weft replenishing looms having, in combination, a bent weft carrierholding spring; a spreader fitting between the'legs of said spring; and a weft carrier directing guide, said guide having upper and lower plates united by the directing incline, said top and bottom plates extending sides downwardly along the sides of the spring shank and thence extending laterally to form flanges adapted to fit within grooves in the shuttle, and the end-of the top plate being bentdownwardly back ofthe curved inner end of the spring, whereby said spring, spreader and guide are united together prior to insertion in the shuttle, and said spreader having a bolt receiving hole adapted to register with the bolt receiving holes in the shank of the spring and said spreader fur,- ther having an inclined end adapted to fit the inner face of the directing incline of the guide. p

2. A shuttle for weft replenishing looms having, in combination, a bent weft carrier holding spring; a spreader fitting between the legs of said spring; and a weft carrier directing guide, said guide having upper and lower plates united by the directing i11- cline, said top and bottom plates extending respectively. above and below the spring and spreader, the upper plate being bent at its sides downwardly along the sides of the spring shank and thence outwardly to con stitute flanges fitting grooves in the shuttle,

and the end of the top plate being bent downwardly back of the inner end of the spring, whereby said spring, spreader and guide are united together prior to insertion in the shuttle, and said spreader having a bolt receiving hole adapted to register with the bolt receiving holes in the shank of the spring and said spreader fitting within the spring and guide so as to be maintained in position with its bolt receiving hole registering with the bolt holes of the spring.

3. A shuttle for weft replenishing looms having, in combination, a bent weft carrier holding spring; a spreader fitting between the legs of said spring; and a bent metal retainer folded around said spring and spreader so as to lock the same together, the top plate of said retainer being bent down wardly outside of the shank of the sprin and outwardly to constitute flanges to fit
